**** Even with drum brakes, it's deemed desirable to keep a residual
pressure in the lines, to keep the brake hardware "at the ready". Although
the dual Lockheed cylinder certainly doesn't need it as much as, say,
a Girling master cylinder from the same era, which just won't work at all
without the valve.
I bet the P.O. thought he was fixing the infamous MGA sticking brakes
syndrome. Which was probably really caused by a swelling cork front plate
gasket.
